According to USGS, as of the end of 2022, the global tin reserves will be 4.6 million tons, which is 52.08% lower than the 9.6 million tons reserves in 2000. Due to long-term mining, traditional tin-producing areas are facing decline in grade, shortage of manpower and rising mining cost and other factors. The tin market size is over 387 kilo tons in 2021 and the market is expected to register a CAGR of over 2.5% during the forecast period (2022-2027).
